How can I change the done button and English description in MPMoviePlayerViewController into “done” and Chinese description?

  ios, question

1. how do I change the done button and English description in MPMoviePlayerViewController into “done” and Chinese description?
2. Can you tell me how to rewrite the fast forward button to fast forward or rewind after tapping, instead of pushing out the view?

Thank you for your answer, thank you very much ~

About 1, try it on a real plane. If it is still not Chinese, open itInfo.plist, add

<key>CFBundleLocalizations</key>
 <array>
 <string>zh_CN</string>
 <string>en</string>
 </array>
